BRAKE-SHOE AND WHEEL-DRESSER.

SPECIFICATION forming part of Letters Patent No. 595,098, dated December 7, 1897.

Application filecl August 18, 1897. Serial No. 648,121. (No model.)

To all whom, it may concern.-

Be it known that I, \VILLIAM E. GORTON, a citizen of the United States, residing at Corning, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Brake'ShOes and \Vheel-Dressers, of which the following is a specification.

My invention relates to a shoe adapted to to operate as a brake and acts while operating as a dresser or trimmer for the wheel, and is particularly applicable to locomotive-wheels, owin to the hardness of the wheel-tire in such cases and to the inconvenience of removing I 5 such wheels to the repair-shop for the purpose of truing up.

To these ends I have devised a brake-shoe formed of cast-iron in which are incorporated during the molding process faces or sections of harder metal, such as steel or chilled castiron, which sections or faces are made flush with the softer faces of the wheel. These sections or faces of harder metal may be termed dressing or trimming tools, as they dress or trim the periphery of the wheel in such a manner as to counterbalance the wear of the rail upon the wheel, and they are designed to operate in such a manner that they will keep pace with the rail-wear and maintain the proper contour and necessary integrity of the periphery at all times.

Specifically my invention consists of two forms of dressing or trimming tools, one of which forms is designed to operate in conjunction with the flange and throat of the wheel and the other is designed to bear upon the outer edge of the wheel, thus leaving the central portion of the wheel, which comes in contact with the rail, practically untouched,

thereby creating a uniformity of rub or friction on the wheel-surface.

In the special construct-ion and arrangement of my dressing and trimming tools lies my invention, which I will now proceed more particularly to describe in connection with the accompanying drawings, which form a part of this specification, and in which- Figure 1 represents a perspective view of my improved brake-shoe. Fig. 2 is a seetional View on the line 2 2, Fig. 1. Fig. 3 is a sectional view on the line 3 3, Fig. 1. Fig.

4: is a sectional View on the line 4 at, Fig. 1. In Figs. 2, 3, and 4 I show the shoe in connection with the wheel-tread. Fig. 5 is a detail perspective View.

In the drawings, A represents a portion of a brake-shoe normally opposed to the outer edge of the wheel, practically coinciding with that part of the wheel which comes in contact with the rail only semi-occasionally. In this portion of the shoe I provide angular cutting or trimming tools B, formed as shown in Figs.

1 and 5. They are approximately triangular in shape and have at the pointb, which is opposed to the ordinary direction of the wheel when in operation, a rounded edge, so as to distribute the cutting at this point more evenly; This tool B is formed of steel or chilled cast-iron and is consequently harder than the body portion A of the brake-shoe, the latter bein formed of ordinary cast-iron. The tool B extends down into the body of the shoe A, as shown at 0. Immediately above the tool B is a slot or channel D, V-shaped and extending down into the body of the shoe, but of a lesser depth than the tool, so'that the shoe When formed will have a shoulder d, which serves as an additional means of locking the tool. Projections E on the angle-tools B further serve to lock same in the softer 80. metal. The faces of the tools B and the shoebody A are made flush one with the other.

I will now proceed to describe the other series. of dressing and trimming tools which I arrange upon the other edge of the brake shoe. These cutting-tools are shown at F and are setinto the brake-shoe so as to overlap the flange G of the wheel and so as to come down and into the throat II of the wheel. These tools F are also made of steel or chilled 0 iron and are supported upon the body of the shoe, first, by being incorporated therewith when the shoe is cast or molded, and as an additional means of support and attachment I provide supporting backs or shoulders J, 5 made of the same form and size as the cutting-tools. I11 the drawings I have shown three of these cutting-tools F and four of the cutting-tools B. Between the cutting and the braking surfaces A and B, which forms the surface exposed to the outer edge of the wheel, and the cuttingtools F which bear upon the flange and throat of the Wheel, is a channel K, extending the entire length of the brakeshoe and so arranged and located that it is opposed to that portion of the Wheel which comes ordinarily in contact with the rail.

It will thus be seen that Iprovide a brakeshoe having soft braking-surfaces combined with hard trimming and dressing surfaces upon those portions of the shoe which are opposed to the Wheel at the edges and outer parts and free as to that portion which forms the central part, and that therefore the tendency of my shoe in operation will be to trim and dress the wheel in the braking action and keep it true at all times. It will also be seen that the channels D, which are immediately above the triangular-shaped cutting and dressing tools B, are adapted to receive the Waste or turnings caused by the friction of the tool upon the wheel and to form a conduit for the same upon one side to the outside of the shoe and upon the other side to the channel K. By this construction also the cutting edges of the tool B are constantly exposed, owing to the spaces being maintained by the slots or channels D immediately contiguous thereto.

It will be seen that the cutting-tools B and F are both pointed in the same direction, and it is the intent of this invention to have the brake-shoes and dressers so formed and employed that the points of the angles of the cutters shall be ordinarily opposed to the direction of the travel of the Wheel of the locomotive.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a combined brake-shoe and Wheeldresser for locomotives, a body formed of cast-iron having cuttingtools of steel or chilled cast-iron set therein substantially as shown and described, said cutting-tools having their edges arranged at an angle to the shoe in cross-section and the apex of said angle pointing in a direction opposed to the ordinary travel of the Wheel, as and for the purpose set forth.

2. In a combined brake-shoe and wheeldresser, the brake-shoe bodyA formed of castiron, with integral cutting or dressing tools F attached to, and supported by, the brakeshoe body substantially as shown and described, and extending down over the flange into the throat of the wheel, as and for the purposes set forth.

3. In a combined brake-shoe and wheeldresser, the brake-shoe body Aformed of castiron, with integral cutting or dressing tools F formed of a harder metal than the body of the shoe and secured in the shoe as shown and described With the supporting shoulders or backs J ,"the said tools and their supporting-shoulders extending down over the flange into the throat of the wheel, as and for the purposes set forth.

4. In a combined brake-shoe and wheeldresser, the brake-shoe bodyA formed of castiron, slots or V-shaped channels D, trimmingtools B formed and located as shown and having shoulders d for locking and retaining the tools and projections E embedded in the softer metal A, all arranged substantially as and for the purposes set forth.
